Description

Technical Field

[0001] This application relates to the field of vehicle body control technology, and in particular to a control method, device, electronic device and readable storage medium for a frameless vehicle door. Background Technology

[0002] Frameless doors are a special design characterized by the absence of a frame, allowing windows to open fully and providing better visibility and ventilation. The design of frameless doors requires specialized technology and consideration. When a user needs to open the door, the window regulator automatically lowers the window a short distance, disengaging it from the door seal, thus eliminating resistance when opening the door. To close the door, simply push it gently against the car body, then wait for the window to automatically rise a short distance, sealing it tightly against the door seal to prevent rain and wind from entering.

[0003] However, the automatic micro-lifting control of frameless car door windows has a certain delay. When a user needs to open the door quickly, the frameless car door window may not react quickly enough to lower a certain distance, thus increasing the overall time it takes for the user to open the door. Therefore, the existing technology suffers from a certain delay in the automatic micro-lifting control of frameless car door windows. Summary of the Invention

[0004] In view of this, embodiments of this application provide a control method, device, electronic device, and readable storage medium for frameless car doors to solve the problem of certain delay in the automatic micro-lifting control of the window glass of frameless car doors in the prior art.

[0005] A first aspect of this application provides a control method for a frameless vehicle door, comprising: acquiring the current driving speed of the vehicle; if the vehicle speed gradually decreases to a second speed after the driving speed is less than a first speed, acquiring the remaining driving distance of the vehicle; determining the remaining driving time of the vehicle based on the remaining driving distance and the second speed; and controlling the window of the frameless vehicle door to descend from a first position to a second position based on the remaining driving time; the first position being in which the window glass is completely inserted into the sealing strip of the vehicle; and the second position being in which the window glass is not inserted into the sealing strip of the vehicle.

[0006] A second aspect of this application provides a control device for a frameless car door, comprising: a first acquisition module for acquiring the current driving speed of the vehicle; a second acquisition module for acquiring the remaining driving distance of the vehicle if the vehicle speed gradually decreases to a second speed after the driving speed is less than a first speed; a determination module for determining the remaining driving time of the vehicle based on the remaining driving distance and the second speed; and a control module for controlling the window of the frameless car door of the vehicle to descend from a first position to a second position based on the remaining driving time; the first position being when the window glass is completely inserted into the sealing strip of the vehicle; and the second position being when the window glass is not inserted into the sealing strip of the vehicle.

[0007] A third aspect of this application provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the above-described method.

[0008] A fourth aspect of this application provides a readable storage medium storing a computer program that, when executed by a processor, implements the steps of the above-described method.

[0009] The beneficial effects of this application embodiment compared with the prior art are as follows: When the vehicle is in motion, the current driving speed of the vehicle is obtained; after detecting that the driving speed is less than a first speed, the speed information of the vehicle in the subsequent period and the second speed of the vehicle after a period of time are obtained; the speed information includes the speed change of the vehicle in a period of time; based on the speed information, the vehicle speed is monitored to show a gradient decreasing trend, thereby predicting whether the person in the car intends to get out of the car. When the navigation is turned on, the remaining driving distance of the vehicle is obtained through the in-vehicle navigation system. Based on the remaining driving distance and the second speed, the remaining driving time of the vehicle is determined, and the vehicle is controlled to lower the window glass of the frameless door from the first position to the second position according to the remaining driving time. By predicting the getting time, the window glass of the frameless door is lowered a certain distance in advance, solving the problem of certain delay in the automatic micro-lifting and lowering control of the window glass of the frameless door in the prior art, reducing the total opening time of the frameless door, ensuring that the person in the car can directly open the door and get out of the car after the vehicle stops, bringing a better user experience and improving user driving satisfaction.

[0016] The following describes in detail, with reference to the accompanying drawings, a control method and apparatus for a frameless car door according to an embodiment of this application.

[0017] Figure 1 This is a flowchart illustrating a control method for a frameless car door provided in an embodiment of this application. Figure 1 As shown, the control method for this frameless door includes:

[0018] Step 101: Obtain the vehicle's current speed.

[0019] In some embodiments, the current speed of the vehicle can be obtained through a speed sensor. The vehicle's speed can convey corresponding information; for example, when a vehicle is traveling at a speed of 100 km / h, it may be traveling on a highway. When a vehicle is traveling at a speed of 5 km / h, the road it is on may be in a traffic jam.

[0020] Step 102: After the driving speed is less than the first speed, if the monitored vehicle speed gradually decreases to the second speed, obtain the remaining driving distance of the vehicle;

[0021] In some embodiments, the first speed can be set according to the actual application scenario, for example, it can be 10 km / h or 15 km / h. However, it should be noted that the first speed does not need to be too high. The frameless door window control method proposed in this application is mainly based on the prediction that the vehicle is about to stop. In this embodiment, the second speed is less than the first speed. Over a period of time, the vehicle's speed decreases from the first speed gradient to the second speed. During the process of the vehicle changing from a driving state to a parked state or a turned-off and stopped state, there will be a period of deceleration until the vehicle stops. Therefore, the second speed can be less than the vehicle's speed at any moment during the aforementioned period of time. After the vehicle's speed decreases from the first speed gradient to the second speed over a period of time, it is possible to predict that the vehicle is about to stop. When the vehicle navigation is on, the remaining driving distance of the vehicle's current journey is determined in real time according to the driving route selected by the user. Obtaining the remaining driving distance and the second speed is a prerequisite for judging the vehicle's subsequent parking time. Predicting the vehicle's parking time allows for the control of the frameless door window within the corresponding time.

[0022] Step 103: Determine the remaining travel time of the vehicle based on the remaining travel distance and the second speed;

[0023] Specifically, the vehicle acceleration can be calculated based on the first speed, the second speed, and related speed information. The related speed information refers to the speed change information during the time the vehicle decreases from the first speed gradient to the second speed. Then, based on this acceleration, the second speed, and the remaining travel distance, the remaining travel time can be calculated. If information such as a traffic accident occurs on the remaining road segment is obtained through navigation traffic data, the remaining travel time can be set as the time required to reach the location of the traffic accident, even before the vehicle reaches its destination. The frameless door windows are controlled based on the remaining travel time, allowing sufficient time for a slight descent.

[0024] Step 104: Based on the remaining driving time, control the window of the frameless door of the vehicle to descend from the first position to the second position; the first position is when the window glass is completely inserted into the sealing strip of the vehicle; the second position is when the window glass is not inserted into the sealing strip of the vehicle.

[0025] Specifically, before the frameless door opens, its window automatically lowers a certain distance, at which point the window glass is in the second position and is not yet engaged with the vehicle's sealing strip. After the door closes, the frameless door window automatically rises a certain distance, at which point the window glass is in the first position and is fully engaged with the vehicle's sealing strip. This fully engaged sealing strip enhances sealing and safety, and provides good sound insulation. After determining the vehicle's remaining driving time, the system controls the vehicle to lower the frameless door window from the first position to the second position within that remaining time.

[0026] In some embodiments, while the vehicle is in motion, the current speed of the vehicle is acquired. After detecting that the speed is less than a first speed, the speed information of the vehicle over a subsequent period and the second speed of the vehicle after a period of time are acquired. The speed information includes the speed changes of the vehicle over a period of time. Based on the speed information, a gradient decreasing trend of the vehicle speed is detected, thereby predicting whether the person inside the vehicle intends to get out. When navigation is activated, the remaining driving distance of the vehicle is acquired through the in-vehicle navigation system. Based on the remaining driving distance and the second speed, the remaining driving time of the vehicle is determined, and the vehicle is controlled to lower the window glass of the frameless door from the first position to the second position based on the remaining driving time. By predicting the getting-out time and lowering the window glass of the frameless door a certain distance in advance, the problem of certain delay in the automatic micro-lifting and lowering control of the window glass of the frameless door in the prior art is solved, the total opening time of the frameless door is reduced, and it is ensured that the person inside the vehicle can directly open the door and get out after the vehicle stops, providing a better user experience and improving user driving satisfaction.

[0027] In some embodiments, controlling the window of the frameless door of the vehicle to descend from a first position to a second position based on the remaining driving time includes: if the remaining driving time is greater than or equal to a first preset time, controlling the window of the frameless door of the vehicle to descend from the first position to the second position at a first descending speed; if the remaining driving time is less than or equal to the first preset time, increasing the descending speed of the window of the frameless door of the vehicle, so that the window of the frameless door of the vehicle descends from the first position to the second position within the remaining driving time.

[0028] Specifically, the first preset time can be set according to the actual scenario. For example, the first descent speed is the normal descent speed of a frameless car window when it descends from the first position to the second position, and the first preset time is the time taken for the frameless car window to descend from the first position to the second position at the first descent speed. If the remaining travel time is greater than or equal to the first preset time, the descent speed of the frameless car window is controlled to be the normal descent speed, i.e., the first descent speed. If the remaining travel time is less than the first preset time, the descent speed of the frameless car window is increased, thereby ensuring that the frameless car window descends from the first position to the second position within the remaining travel time, ensuring that people inside the vehicle can directly open the door and exit after the vehicle stops.

[0029] In some embodiments, before controlling the window of the frameless door of the vehicle to descend from a first position to a second position based on the remaining driving time, the method further includes: obtaining information on the number of people inside the vehicle and the corresponding position of each person inside the vehicle; and, based on the position and the remaining driving time, causing the window next to the corresponding position of each person inside the vehicle to descend from the first position to the second position.

[0030] Specifically, the vehicle includes a front left window, a front right window, a rear left window, and a rear right window. An in-vehicle camera is installed inside the vehicle. The images captured by the in-vehicle camera are analyzed to determine the number of people inside the vehicle and their positions. For example, if there are two passengers inside the vehicle, one in the front left seat and one in the front right seat, based on their positions and the calculated remaining travel time, the front left window is lowered from its first position to its second position, and the front right window is lowered from its first position to its second position. Similarly, the front right window is lowered from its first position to its second position. Controlling the slight lowering of the corresponding frameless door windows based on the positions of the people inside the vehicle improves convenience and prevents unnecessary lowering of the frameless door windows.

[0031] In some embodiments, before controlling the window of the frameless door of the vehicle to descend from the first position to the second position based on the remaining driving time, the method further includes: obtaining the weather at the current location of the vehicle; continuing to execute the step of controlling the window of the frameless door of the vehicle to descend from the first position to the second position based on the remaining driving time when the weather is detected to be sunny, cloudy, or overcast; and stopping the step of controlling the window of the frameless door of the vehicle to descend from the first position to the second position based on the remaining driving time when the weather is rainy, snowy, sandstorm, dust, haze, or strong wind.

[0032] Specifically, the vehicle's current weather location can be obtained via the internet, and the vehicle's onboard LiDAR can detect the weather at the vehicle's current location, controlling the frameless door windows accordingly. If the current weather is sunny, cloudy, or partly cloudy, indicating good external weather conditions, the frameless door windows will be lowered from position one to position two. However, if the current weather is rainy, snowy, a sandstorm, dusty, hazy, or windy, indicating unsuitable external weather conditions, lowering the frameless door windows from position one to position two may allow rainwater, snow, dust, or haze to enter the vehicle, potentially negatively impacting the interior hygiene or air quality. Therefore, if the weather at the current location is rain, snow, sandstorm, dust, haze, or strong wind, the step of controlling the frameless door window of the vehicle to descend from the first position to the second position based on the remaining driving time will be stopped, so that the frameless door window of the vehicle remains in the first position, preventing the adverse weather conditions outside from affecting the interior environment of the vehicle before the vehicle stops driving.

[0033] In some embodiments, before controlling the window of the frameless door of the vehicle to descend from the first position to the second position based on the remaining driving time, the method further includes: determining whether the vehicle receives a collision signal during driving; and if it is determined that a collision signal has been received, continuing to execute the step of controlling the window of the frameless door of the vehicle to descend from the first position to the second position based on the remaining driving time.

[0034] Specifically, during vehicle operation, it is determined whether the vehicle has received a collision signal. For example, when the vehicle collides with an obstacle or is rear-ended by another vehicle, the collision sensor will detect the impact force of the collision and send a collision signal to the vehicle. If the vehicle receives a collision signal, based on the remaining driving time, the frameless door window of the vehicle is controlled to descend from a first position to a second position, providing additional safety for the occupants. Descending the frameless door window from the first position to the second position facilitates the opening of subsequent vehicle doors and the exit of occupants.

[0035] In some embodiments, when the vehicle is in a parked and off state, an image of a person in a first area is acquired by an in-vehicle camera; the person is identified by the image to determine whether the person is the target person; if the person is determined to be the target person, image information of the person in a second area is acquired; the range of the second area is smaller than the range of the first area; the target intention of the person is determined based on the image information; if the target intention is to get into the vehicle, the window of the frameless door of the vehicle is controlled to descend from a first position to a second position.

[0036] Specifically, when the vehicle is turned off and parked, the engine stops, some electronic devices are switched off, while others remain on, such as the vehicle-mounted camera located outside the vehicle. When the vehicle is off and parked, and there are no people inside, the frameless door window is in the first position, with the window glass fully embedded in the vehicle's sealing strip. The vehicle-mounted camera remains operational, monitoring the surrounding environment and acquiring images of people within the first area. In some embodiments, the vehicle-mounted camera mainly includes a lens assembly, an image sensor, an image signal processor, and connectors. This application does not limit the position or number of cameras; in specific situations, the number of cameras used in this method can be determined by considering factors such as the camera's viewing angle and pixel count. The first area is set according to the specific application scenario; for example, the first area can be a circular area with a radius of 5 meters centered on the vehicle. After the vehicle-mounted camera detects a person entering the first area, it captures an image of the person within the first area, which in this application can be a facial image. After acquiring images of individuals within a first-zone area using the vehicle's in-vehicle camera, the camera uses an algorithm to authenticate these individuals, determining if they have previously registered with the vehicle. The vehicle can support multiple registrations, which can refer to the registration of the vehicle owner, typically the driver. If the individual is identified as the target, the in-vehicle camera acquires their image information within a second-zone area, smaller than the first. For example, if the first zone has a radius of 5 meters centered on the vehicle, the second zone can be set to a radius of 3 meters. Based on the image information, the camera determines the individual's intention. If the intention is to get into the vehicle, the frameless door window is lowered from a first position to a second position. This slight lowering of the window facilitates the opening of the door, providing a convenient, safe, and intelligent service to the user.

[0037] In some embodiments, determining a person's target intention based on image information includes: obtaining the person's action features based on the image information, determining the similarity between the person's action features and preset action features in the database; and determining that the person's target intention is to get on the vehicle if the similarity is greater than a preset value.

[0038] Specifically, in some cases, a person's behavior can be predicted based on their actions. This method can be applied to predicting a person's intention to get into a vehicle. Several preset action features are stored in a database. These preset action features represent the actions of a tested person who intends to open the car door and get in. After acquiring the image information of the person in a second region, a feature vector of the image information is constructed based on the image information. This feature vector is then compared with the feature vector of the preset actions to determine the similarity between the person's action features and the preset action features in the database. If the similarity is greater than a preset value, the person's intended purpose is determined to be getting into the vehicle. This application does not impose restrictions on the preset value; in practical applications, it is set based on test results.

[0039] In some embodiments, after controlling the window of the frameless door of the vehicle to descend from the first position to the second position, the method further includes: if no door opening is detected within a second preset time, controlling the window of the frameless door of the vehicle to rise from the second position to the first position; and if a door opening is detected within the second preset time, storing the person's motion characteristics in a database and determining them as preset motion characteristics.

[0040] Specifically, the second preset time period can be set to 5 minutes or 10 minutes; this application does not impose any specific restrictions on this. If the frameless car door window is kept in the second position for an extended period, meaning the window glass is not secured within the vehicle's sealing strip, dust and rainwater from outside may enter the vehicle, negatively impacting the interior hygiene. Therefore, if no door opening is detected within the second preset time period, it indicates that the authenticated person does not intend to open the door and get in, making it necessary to raise the frameless car door window from the second position to the first position. If a door opening is detected within the second preset time period, it indicates that the person's action characteristics suggest an intention to open the door and get in. These action characteristics are stored in the database and identified as preset action characteristics, enriching the database's storage and updating it according to actual conditions.

[0041] All of the above-mentioned optional technical solutions can be combined in any way to form the optional embodiments of this application, and will not be described in detail here.

[0042] Figure 2 This is a schematic diagram of a vehicle in an embodiment of this application. The vehicle may include a speed sensor 201, a vehicle controller 202, a smart cockpit domain controller 203, an autonomous driving domain controller 204, a body domain controller 205, a chassis domain controller 206, a collision sensor 207, an in-vehicle camera 208, a window 209, and an on-board camera 210.

[0043] The speed sensor 201 is connected to the vehicle controller 202 and can monitor the vehicle's speed in real time and transmit the speed information to the vehicle controller 202. In this embodiment, the speed sensor 201 acquires the vehicle's current speed and transmits the speed information to the vehicle controller 202.

[0044] The vehicle controller 202 is one of the core controllers of the vehicle. It monitors and controls the operating status of the system and coordinates the work of various domain controllers. It communicates with the intelligent cockpit domain controller 203, the autonomous driving domain controller 204, the body domain controller 205, and the chassis domain controller 206 to ensure smooth vehicle operation. In some embodiments, the vehicle controller 202 receives the vehicle's current speed from the speed sensor 201 and transmits the speed information to the body domain controller 205.

[0045] The intelligent cockpit domain controller 203 is mainly responsible for the implementation of intelligent cockpit functions. The intelligent cockpit domain controller 203 is connected to the in-vehicle camera 208 located in the vehicle. The in-vehicle camera 208 obtains the number and location information of people in the vehicle through the image information it captures, and can transmit the number and location information to the vehicle body domain controller 205.

[0046] The autonomous driving domain controller 204 possesses capabilities for multi-sensor fusion, localization, path planning, decision control, wireless communication, and high-speed communication. It can process data required for autonomous driving, including but not limited to data from millimeter-wave radar, vehicle-mounted camera 210, lidar, inertial navigation, and other devices. The autonomous driving domain controller 204 is connected to the vehicle-mounted camera 210 and the body domain controller 205. After receiving image information of people and other data from the vehicle-mounted camera 210, the autonomous driving domain controller 204 transmits it to the body domain controller 205.

[0047] The body domain controller 205 can perform functions including driver assistance, infotainment, control of door locks, window 209 raising and lowering, lights, etc. The body domain controller 205 is connected to the window 209 and controls the raising and lowering of the window 209 according to the relevant instructions received. For example, based on the first control instruction, it controls the vehicle to lower the window 209 of the frameless door of the vehicle from the first position to the second position before the expected parking time.

[0048] The chassis domain controller 206 is connected to the body domain controller 205 and the collision sensor 207. When the vehicle collides with an obstacle or is rear-ended by another vehicle, the collision sensor 207 will sense the impact force of the collision and transmit the collision signal to the chassis domain controller 206. The chassis domain controller 206 generates a corresponding command and sends the command to the body domain controller 205. Based on the command, the body domain controller 205 lowers the window 209 of the frameless door of the vehicle from the first position to the second position.

[0049] The following are embodiments of the apparatus described in this application, which can be used to execute the embodiments of the method described in this application. For details not disclosed in the apparatus embodiments of this application, please refer to the embodiments of the method described in this application.

[0050] Figure 3 This is a schematic diagram of a frameless car door window device provided in an embodiment of this application. Figure 3 As shown, the window assembly of the frameless car door includes:

[0051] The first acquisition module 301 is used to acquire the current driving speed of the vehicle;

[0052] The second acquisition module 302 is used to acquire the remaining driving distance of the vehicle if the vehicle speed gradually decreases to the second speed after the driving speed is less than the first speed.

[0053] The determination module 303 is used to determine the remaining driving time of the vehicle based on the remaining driving distance and the second speed;

[0054] The control module 304 is used to control the window of the frameless door of the vehicle to descend from a first position to a second position based on the remaining driving time; the first position is when the window glass is fully inserted into the sealing strip of the vehicle; the second position is when the window glass is not inserted into the sealing strip of the vehicle.

[0055] According to the technical solution provided in this application embodiment, when the vehicle is in motion, the first acquisition module 301 acquires the vehicle's current speed; after detecting that the speed is less than a first speed, the second acquisition module 302 acquires the vehicle's speed information over a subsequent period and the vehicle's second speed after a period of time; the speed information includes the vehicle's speed changes over a period of time; based on the speed information, the vehicle's speed is detected to have a gradient decreasing trend, thereby predicting whether the person inside the vehicle intends to get out. When navigation is activated, the remaining driving distance of the vehicle is acquired through the in-vehicle navigation system. Based on the remaining driving distance and the second speed, module 303 determines the remaining driving time of the vehicle. Then, control module 304 controls the vehicle to lower the frameless door window from the first position to the second position based on the remaining driving time. By predicting the exit time, the frameless door window is lowered a certain distance in advance, which solves the problem of certain delay in the automatic micro-lifting and lowering control of the frameless door window in the prior art. This reduces the total opening time of the frameless door, ensuring that people inside the vehicle can directly open the door and get out after the vehicle stops, providing users with a better user experience and improving user satisfaction.

[0056] In some embodiments, the control module 304 is configured to control the window of the vehicle's frameless door to descend from a first position to a second position at a first descending speed if the remaining driving time is greater than or equal to a first preset time; and to increase the descending speed of the window of the vehicle's frameless door if the remaining driving time is less than or equal to the first preset time, so that the window of the vehicle's frameless door descends from the first position to the second position within the remaining driving time.

[0057] In some embodiments, the second control module is further configured to obtain the weather at the current location of the vehicle before controlling the window of the frameless door of the vehicle to descend from the first position to the second position based on the remaining driving time; if the weather is detected to be sunny, cloudy, or overcast, continue to execute the step of controlling the window of the frameless door of the vehicle to descend from the first position to the second position based on the remaining driving time; and if the weather is rainy, snowy, sandstorm, dust storm, haze, or strong wind, stop executing the step of controlling the window of the frameless door of the vehicle to descend from the first position to the second position based on the remaining driving time.

[0058] In some embodiments, the third control module is further configured to determine whether the vehicle has received a collision signal during driving before controlling the window of the frameless door of the vehicle to descend from the first position to the second position based on the remaining driving time; if it is determined that a collision signal has been received, the step of controlling the window of the frameless door of the vehicle to descend from the first position to the second position based on the remaining driving time continues to be executed.

[0059] In some embodiments, a fourth control module is further configured to, when the vehicle is in a turned-off and parked state, acquire an image of a person in a first area via an in-vehicle camera; authenticate the person's identity using the image to determine if the person is the target person; if the person is determined to be the target person, acquire image information of the person in a second area; the range of the second area is smaller than the range of the first area; determine the target intention of the person based on the image information; and if the target intention is to get into the vehicle, control the window of the frameless door of the vehicle to descend from a first position to a second position.

[0060] In some embodiments, the fourth control module is configured to obtain the action features of a person based on image information, determine the similarity between the action features of the person and preset action features in the database, and determine that the person's target intention is to get on the vehicle if the similarity is greater than a preset value.

[0061] In some embodiments, the fourth control module is configured to control the window of the frameless door of the vehicle to rise from the second position to the first position after the window has been lowered from the first position to the second position and no door opening has been detected within a second preset time period; and if a door opening is detected within the second preset time period, to store the person's motion characteristics in the database and determine them as preset motion characteristics.

[0062] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
